Actually coheed if you do the 04+ trans the gearing is nearly identical to a p11 trans with the addition of 6th gear. Go look at the charts on it. You have to realize we rev out 1500rpms higher than a stock spec v does with an 8k rev limit. Even more with a 9k or higher.
8k in 6th gear on the 04 trans is 242mph or so. Again i could cross the 1/4 still in 4th on a 25" slick. Should be good to 160+ on that slick as well in 4th. Which is plenty
